Dilemma

The horns of a dilemma. “Lemma” means a thing taken for granted
(Greek, lambano, to take). “Dilemma” is a double lemma, a
two-edged sword which strikes both ways, or a bull which will toss you
whichever horn you lay hold of. A young rhetorician said to an old
sophist, “Teach me to plead, and I will pay you when I gain a cause.”
The master sued for payment, and the scholar pleaded, “If I gain the
cause I shall not pay you, because the judge will say I am not to pay,
and if I lose my cause I shall not be required to pay, according to the
terms of our agreement.” To this the master replied, “Not so; if you
gain your cause you must pay me according to the terms of our
agreement; and if you lose your cause the judge will condemn you to pay
me.”
